Idle economizer control unit 5013.3761

General information:

The idle economizer control unit (IECU) 5013.3761 is purposed for switching on / off of idle economizer electromagnetic valve in order to increase saving of fuel and reduce toxicity of vehicle exhaust gases.

Application: automobiles VAZ-2104, VAZ-2105, VAZ-2107, VAZ-2121 and others with carburettor “Solex”.

Idle economizer control unit 5013.3761 ensures:
- 
control of the idle economizer electromagnetic valve;
- 
of the idle economizer valve control circuit from a short-circuit on "mass" of the vehicle;
- 
from resistance reduction of idle economizer valve circuit;

The idle economizer control unit is produced in a single climatic design O2.1 in accordance with GOST 15150 for internal market and for export. An operating mode of the IECU is S1 in accordance with DSTU GOST 3940.

The idle economizer control unit 5013.3761 is mounted on a stipulated for it place in the vehicle with the help of standard fastenings and a standard plug.

The warranty period of exploitation is 3 years from the date of commissioning or from the date of sale in retail commercial network. The warranty obligations of the manufacturer are valid during four years from the date of the item production. The date of production is marked on the case of the item housing.
